That scan is only showing the one flv file recovered
Have you tried playing the recovered video to see just what it is?
Flv is a Flash video format, VLC should be able to play it as is or it could be converted to an mp4.
You can download VLC here if you don't already have it, its free: <a href="https://www.videolan.org/" ipsnoembed="true" rel="external nofollow">https://www.videolan.org/</a>
We need you to explain a bit more to be able to advise what may be the best way to proceed to find the rest of the files (if possible).
What type of drive is this. a HDD, an SSD, memory stick. SD card, other?
Why are you attempting a recovery? ie. Had you accidently deleted some files? Had the drive crashed? Some other reason?
The methods/techniques you need to use will be different depending on just how/why the files went missing.
What has happened, if anything, with the drive between losing the files and attempting a recovery with Recuva?
ie. Have you continued using the drive if the files were deleted accidentally?, have you reformatted the drive if it had crashed?, had you tried using any other recovery software before Recuva? etc.
When running Recuva did you use the Wizard or the Advanced Options?
If using the Advanced Options then exactly how did you set it to run a scan?
